Summary:The invention discloses a high-stability double-helix DNA model for biological teaching, belonging to the field of DNA models. According to the high-stability double-helix DNA model for biological teaching, by arranging an elastic middle part and a transverse chain shaft, on one hand, the difficulty of inserting the transverse chain into the axial DNA longitudinal skeleton can be effectively reduced, so that the assembling efficiency of the model is effectively improved; another aspect, after assembly, the transverse chain shafts, the inner suction hemisphere blocks and the inner locking positioning lines are matched; after the transverse chain shaft is inserted into the DNA longitudinal skeleton, the transverse chain shaft and the inner locking bit line are mutually wound; the transversechain shaft is effectively prevented from falling off from the DNA longitudinal skeleton; and under the action of mutual magnetic attraction force, the winding effect between the internal locking positioning line and the tran
